MACARONI DIE.

Application filed January 23, 1928.

|This invention relates to machinery for the manufacture from plastic dough of food products such as macaroni and the like, and more particularly relates to the means employed therein for giving a characteristic shape or structure to said products.

Said products are generally made by the agency of a dough press, which in one of its common forms comprises a cylinder for containing the dough in a plastic condition and means for exerting pressure on said dough so that it is caused to be expelled through apertures or dies formed in a die plate located at the discharging end of said cylinder. Inasmuch as said machinery and the dough press are well known in the art, l hare not shown nor described the saine at length in the drawings and specification of this application.

My invention more particularly pertains to the construction ofthe dies or dough discharging apertures formed in the die plates through which the dough in said machines is expelled from the doughY presses. As is well known in the art, said die plates are of a size adapted to close the end of the dough press cylinder, and in said die plate are formed a plurality of dies which are distributed over the die plate'in such numbers as the form and nature of the die and the relative area required in the die plate for the same permit.

The object of my invention is to provide a. novel construction of the die which shapes the dough forced there through from the dough-press into a macaroni or other like product having the distinctive characteristics which are hereinafter set forth; which macaronis are f designated by the trade naine Juliet.

As my invention, as above mentioned relates wholly to the dies used in shaping the macaroni., I have in this application confined the drawings and specification to the illustration and description of the characteristic construction and formation of a single die. It is to be understood, however, that such die is but one among' a plurality of other like dies formed in said die plate, all of which have the construction and formation characteristic of CII said single die. My invention, therefore, con- Serial No. 248,855.

inafter described, particularly pointed out in the claims, and shown in the accompanying drawings. I

In said drawings, in which like reference characters, so far as practicable, designate the corresponding parts in the several views:

'Fig'. l is a fragment of the die plate, viewed toward the dough entering side thereof. and showing l cated embodying my invention in its preferred form.

Fig. 9 is a similar sectional view of the macaroni produced by my dies in its 1nodified form shown in Figures 4, 5 and G.

Figures l() and 1l are similar sectional views of the macaroni product produced by further modified forms of my dies.

in said drawings l is a fragment of the die plate showing a single die constructed therein. The discharge aperture of the die. in its preferred construction is in the form of a. cruciform ope/Larg comprising a narrow longitudinal slot 2, which is crossed substantiail midway of its length in the short cross slot n channel 4 of an area approximately equivalcnt to that of the shortl cross slot B extends through the die plate l, from its intake side, (meaning thereby the side thereof against which the dough from the dough press is forced) and leads to and teminatcs in the portion of said aperture formed by said cross slot. l

Die feeding apertures or recesses 5, 5, which may be formed by drilling from the intake side of the die plate, traverse substantially the 'thickness of the plate, with the apex of therein a single die one such recess located over one end of the longitudinal slot Q and with the apenV of the other recess portioned over the other end of said slot.

A passage, 6, extends laterally from each of said die feeding apertures and is carried downwardly to, and terminates in the portion or' the longitudinal slot 2 lyingl intermediateA an end and the cross slot. 3. Said passage 6, is also arranged to extend to and communicates with the adjacent side ot the channel 4i. lllhile in the drawings have 'lor the salie ot' clarity shown said passage 6, G, as oi' greater widtlrthan that of the slot 2 and 3 embodied in the discharge orilice, the widths of said passages t3, 6, and saidslots are in reality practically identical.

lVhile, as has been aliiove pointed out the central, channel el is approxinuit-ely ot equal arca with that ot the cross slot Q, each ot the die 'feeding apertures is, on the contrary, ot relatiwly.large area in conuiarison with the arca of the longitudinal slot with which it communicates. Owing to these considera- 'tions the dough, in passing through my ini- ]n'oved die7 is controlled in the Vtfflluwing manner so that it emero'es 'trom the die aperture in the characteristic i'iorni shown in side view hy F 7. In the iliormation o't inacaroni hy the use o't' my die, the pressure exerted on the dough by the dough press, 'torces a portion o't it into the channel l, and atter traversing the same it is discharged through the short cross slot and 'torina the central rio A oit the pi'oduct shown in Figs. 7 and 8. its a result oit the same pressure, dough is also forced into the die t'eeding recesses 5, 5, whence it flows out, in part laterally through the passages G, G, to unite with the dough in the channel Zl, and in part downwardly through said passages G, (S, to be ldischarged through the arms et the longituiiliiuil slot 2, by which terms l designate the portions thereof which lic on either side oi the short cross-slot 8.

wing to the large area oit the die 'teeding recess-es 5, 5. relative to the end porticais, or arms. ot the longitudinal slot 2, to which they supply dough, there is a tendency ttor the dough to eii'ierge more 'freely 'from said arms than trom said cross slot 3, to which it is supplied through the channel Zl. ln other words, the substantial. equivalence oit the area ot the channel l and of the area ot the cross-slot 3, to which it feeds the dough, produces in ettect a drag upon the dough dischargingthrough the cross slot 3 and forming the central rib A of the product, which causes a slowing up of the rate of discharge of the same as compared with the rate ol' discharge o't the dough from the arms'oil the longitudinal slot. ln consequence of their more rapid rate ot discharge, the dough strips emerge from said end. portions of slot 2 in the form of wing portions ext-ending laterally from and lying in `way oli the length of the longitudinal Locas-i9 waving `folds on each side of the relatively straight central rib A, which forms, as it were, the back-bone of the product. Y A

In the modiiication of my invention shown in Figs. 1l, 5 and 6, the cross-slot 3, of the die, is replaced by the preferably circular enlargement or opening' 7 located substantially inidslot Q. This enlargement or opening 7 performs the saine function the, short cross-slot 3 which is a. part oit the aperture presented by the die shown in Figs. l, 2 and 3, in Yforming at the center ofi the macaroni product emerging n from the die, the center rib B (see Fig. 9) of i substantially cylindrical form; from which extends on either side the wing portions with waving folds formed by the end arms of the longitudinal slot. An end view of this type out product is illustrated in Figure 9. Further, by the use oit.' a pin S, secured in said die plate so that its end is centrally located. in said. circular enlargement 7, the said central rih ll may be 'formed with an axial hollow bore 9 extending throughout its length and resulting in a 'toi-mation of said central rib similar to the common type of tubular inacaronis.

Figures l0 and ll show,` in sectional views analogous to` those in Figs. 8 and 9, macaronis having the construction' characteristic of the products oi' the dies which embody my invention, but embodying central ribs which differ; in form from those shown in the gures hereinbel'ore described.

In Fig. 10, the centraly rib C is shown as being substantially hexagonal in orin, instead ot' being in the circular form shown in Fig. 9. This modification is secured by the simple change o't the outline of the central enlargenient embodied in the die aperture shown in Fig. G from that of a substantially circular opening to one which is of a hexagonal outline. The change in the die is oil-such an obvious nature that it appears unnecessary yto illustrate or describe in detail inthis specification tlie specific form ot the diercalculated to produce this 'torni of product.`

In similar manner Fig. ll shows a central rib D having the still further modification in .torni so that its cross section is of the shape oi a lozcnge, which is obtained by another corresponding inoditication in the form of the cent-ral enlargement or" the die aperture.Y In this torm of central rib, it is, moreover, of ad-` vantage to provide twin longitudinal bores l0, extending throughout the length` of the rib, as may be shown in said Fig. 1l.

Having described myvinvention what I' claim and desire to secure by Letters Patent is: l
